TECHNICAL FIELD

This invention relates to a server device, a user device, a method for controlling a server device, a recording medium, and a system.

BACKGROUND

Servers that provide games to portable devices via communication networks have been widespread in recent years. Games provided by such servers include, for example, reward winning games (including those generally known as “Gachagacha (registered trademark in Japan)”) (for example, refer to Japanese Unexamined Patent Publication No. 2012-221132). Arewardwinning game is a game in which a reward selected from aset of rewards by random lottery is given to a user.

Recently, a package-type reward winning game has been proposed in which a list showing the kinds of rewards and the number of rewards to be given is presented in advance to the user and rewards selected from the list are given to the user without duplication among the rewards. More specifically, in the package-type reward winning game, a package (a set or group) of rewards is made available for each user, and any reward once given to the user is deleted from the package so that the same reward will not be given to the user in a duplicate manner. The package-type reward winning game has the feature that no duplication occurs among the rewards won and that a user can eventually receive even rare rewards without fail.

SUMMARY

In the package-type reward winning game, a user is allowed to reset the package. The user is also allowed to replace the package with another package. However, in either case, the user has to try the reward winning game over again from the beginning. Accordingly, for example, if the user wants to regain any reward already won or wants to receive a reward not included in the package, the user cannot receive such rewards unless the user abandons all of the rewards so far won. In this way, the prior art reward winning game lacks flexibility and limits the user's activity. As a result, with the prior art reward winning game, it has been difficult to maintain the user's interest by providing a new package, etc., and there has therefore been the possibility that the user may soon become bored with the game.

The present invention has been devised to overcome the above prior art problem, and an object of the invention is to provide a server device, a user device, a method for controlling a server device, a recording medium, and a system capable of enhancing flexibility of a reward winning game and maintaining user's interest in the game.

DESCRIPTION

Hereinafter, with reference to the drawings, a server device, a user device, a method for controlling a server device, a recording medium, and a system will be described. It should be noted that the technical scope of the present invention is not limited to embodiments of the invention but covers the invention described in the claims and its equivalent.

In the present embodiment, the user plays a package-type reward winning game. Further, the user updates the package as needed. A portable device, in accordance with an instruction from the user, requests a server to give a reward, update the package, etc. In response to the request received from the portable device, the server performs processing for giving a reward, updating the package, etc.

The updating of the package is performed by applying a modified package to the package. The modified package defines a set of rewards and the type of operation (“addition”, “deletion”, or “replacement”) to be applied to the existing package, and is classified as an addition package, a deletion package, or a replacement package according to the type of operation. The addition package is one that adds a reward to the existing package. The deletion package is one that deletes a reward from the existing package. The replacement package is one that replaces a reward included in the existing package by another reward.

The user can obtain such a modified package by various means. For example, the user can obtain it by playing a battle game. Further, the user can possess more than one modified package. The user can use the possessed modified package at any desired time. In this way, by making it possible to apply various types of operation such as the addition of rewards to the existing package by using such modified packages, the flexibility of the reward winning game can be enhanced.

FIGS. 6a to 6k are diagrams showing an example of how the state of a package transitions.

FIG. 6a shows the initial state of the package. The package includes rewards “a” to “h”.

Suppose that a reward winning game was applied to this package (FIG. 6b ) and the reward “c” was won. FIG. 6c shows the resulting state of the package. The reward “c” has been deleted from the package.

Next, suppose that a modified package (addition package) for adding rewards “i” and “j” was applied to the package (FIG. 6d ). FIG. 6e shows the resulting state of the package. The rewards “i” and “j” have been added at the end of the package.

Next, suppose that a modified package (deletion package) for deleting the rewards “e” and “f” was applied to the package (FIG. 6f ). FIG. 6g shows the resulting state of the package. The rewards “e” and “f” have been deleted from the package.

Next, suppose that a modified package (replacement package) for replacing the reward “h” by a reward “k” was applied to the package (FIG. 6h ). FIG. 6i shows the resulting state of the package. The reward “h” included in the package has been replaced by the reward “k”.

Lastly, suppose that a package resetting operation was applied to the package (FIG. 6j ). FIG. 6k shows the resulting state of the package. The rewards “c”, “e”, and “f” that have been deleted as a result of the application of the reward winning game and the deletion package are now reinstated in the package. On the other hand, the rewards “i” and “j” added as a result of the application of the addition package and the reward k included by replacement as a result of the application of the replacement package are retained in the package.

However, the rewards added as a result of the application of the addition package or included by replacement as a result of the application of the replacement package may not be retained in the package. For example, the package may be reset to the initial state.

To implement the above-illustrated functions, the server processing unit 33 includes a control unit 331, a game starting unit 332, a game proceeding unit 333, a rewarding unit 334, a package confirming unit 335, a package updating unit 336, and a package resetting unit 337. These units are functional modules implemented by a program executed on the processor included in the server processing unit 33. Alternatively, these units may be implemented as firmware in the server 3.

The process performed by the control unit 331 will be described below. The control unit 331 controls the proceeding of the reward winning game, and instructs the game starting unit 332, the game proceeding unit 333, etc., to perform necessary processing.

When a user authentication request is received from the portable device 2 via the server communication unit 31, the control unit 331 interprets the received user authentication request and identifies the user ID and password. Then, by using the identified user ID and password as parameters, the control unit 331 instructs a user authenticating unit (not shown) to perform the necessary processing.

When the user has been authenticated by the user authenticating unit, the control unit 331 instructs the game starting unit 332 to execute the corresponding process by using the identified user ID as a parameter.

The control unit 331 transmits the home screen display data returned from the game starting unit 332, to the portable device 2 via the server communication unit 31.

On the other hand, when a game proceeding request is received from the portable device 2 via the server communication unit 31, the control unit 331 instructs the game proceeding unit 333 to execute the corresponding process by using the received game proceeding request as a parameter.

The control unit 331 transmits the screen display data for giving reward, etc., returned from the game proceeding unit 333, to the portable device 2 via the server communication unit 31.

The process performed by the game starting unit 332 will be described below. The game starting unit 332 tabulates the winning status of the rewards included in the package, and creates display data for the home screen that displays the results along with the buttons for accepting various instructions.

The game starting unit 332 creates the home screen display data. More specifically, the game starting unit 332 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Further, the game starting unit 332 refers to the giving status of the rewards included in the identified user's package, and identifies “not-yet-given” and “given” rewards, respectively. Next, the game starting unit 332 refers to the reward table stored in the server storage unit 32 by using the ID of each identified reward as the key, and extracts the name of the corresponding reward and the filename of the associated image data. Then, the game starting unit 332 creates the home screen display data, including the received user ID, etc., for displaying the name of each identified reward, the image designated by its filename, the numbers (the number of pieces so far given versus the sum of the number of pieces so far given and the number of pieces not yet given), the buttons for accepting various instructions (rewarding, package confirmation, updating, and resetting), etc., in a prescribed layout.

The game starting unit 332 terminates the process after returning the created home screen display data to the control unit 331.

The process performed by the game proceeding unit 333 will be described below. The game proceeding unit 333 causes the reward winning game to proceed in accordance with a game proceeding request.

The game proceeding unit 333 interprets the received game proceeding request and identifies the type of instruction and the user ID. If the type of instruction identified is the “rewarding”, the game proceeding unit 333 instructs the rewarding unit 334 to execute the corresponding process by using the identified user ID as a parameter.

On the other hand, if the type of instruction identified is the “package confirmation”, the game proceeding unit 333 instructs the package confirming unit 335 to execute the corresponding process by using the identified user ID as a parameter.

On the other hand, if the type of instruction identified is the “modified package selection”, the game proceeding unit 333 instructs the package updating unit 336 to execute the corresponding process by using the type of instruction identified and the identified user ID as parameters.

On the other hand, if the type of instruction identified is the “modified package application”, the game proceeding unit 333 interprets the received game proceeding request and identifies the modified package ID as well. Then, the game proceeding unit 333 instructs the package updating unit 336 to execute the corresponding process by using the type of instruction identified, the identified modified package ID, and the identified user ID as parameters.

On the other hand, if the type of instruction identified is the “package resetting”, the game proceeding unit 333 instructs the package resetting unit 337 to execute the corresponding process by using the identified user ID as a parameter.

On the other hand, if the type of instruction identified is none of the above, i.e., if it is the “return to home screen”, the game proceeding unit 333 instructs the game starting unit 332 to execute the corresponding process by using the identified user ID as a parameter.

The game starting unit 332 terminates the process after passing the screen display data for giving reward, etc., returned from the rewarding unit 334, etc., on to the control unit 331.

The process performed by the rewarding unit 334 will be described below. The rewarding unit 334 gives a reward selected from the package to the user, and creates display data for the rewarding screen that displays the result.

The rewarding unit 334 gives the reward to the user. More specifically, the rewarding unit 334 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Further, the rewarding unit 334 refers to the giving status of the rewards included in the identified user's package, and identifies “not-yet-given” rewards. Then, the rewarding unit 334 selects a reward from among the identified rewards by random lottery by using a pseudo-random number generated using the current time or the like as a seed. The rewarding unit 334 stores the ID of the selected reward as the ID of the reward given to the identified user. Further, the rewarding unit 334 changes the giving status of the selected reward to “given”.

The rewarding unit 334 creates the screen display data for giving reward. More specifically, the rewarding unit 334 refers to the reward table stored in the server storage unit 32 by using the ID of the selected reward as the key, and extracts the name of the corresponding reward and the filename of the associated image data. Then, the rewarding unit 334 creates the screen display data for giving reward, including the received user ID, etc., for displaying the extracted name, the image designated by its filename, the text to the effect that the reward has been won, the button for accepting the “return to home screen” instruction, etc., in a prescribed layout.

The rewarding unit 334 terminates the process after returning the created screen display data for giving reward to the game proceeding unit 333.

The process performed by the package confirming unit 335 will be described below. The package confirming unit 335 tabulates the remaining status of the rewards included in the package, and creates display data for the package confirmation screen that displays the results.

The package confirming unit 335 creates the screen display data for confirming package. More specifically, the package confirming unit 335 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Further, the package confirming unit 335 refers to the giving status of the rewards included in the identified user's package, and identifies “not-yet-given” and “given” rewards, respectively. Next, the package confirming unit 335 refers to the reward table stored in the server storage unit 32 by using the ID of each identified reward as the key, and extracts the name of the corresponding reward and the filename of the associated image data. Then, the package confirming unit 335 creates the screen display data for confirming package, including the received user ID, etc., for displaying the name of each identified reward, the image designated by its filename, the numbers (the number of pieces not yet given versus the sum of the number of pieces so far given and the number of pieces not yet given), the button for accepting the “return to home screen” instruction, etc., in a prescribed layout.

The package confirming unit 335 terminates the process after returning the created screen display data for confirming package to the game proceeding unit 333.

The process performed by the package updating unit 336 will be described below. The package updating unit 336 creates display data for the modified package selection screen that presents a list of available modified packages to the user and prompts the user to select a desired one from it. Further, the package updating unit 336 updates the package by using the selected modified package, tabulates the remaining status of the rewards included in the package, and creates display data for the package updating screen that displays the results.

If the type of instruction is the “modified package selection”, the package updating unit 336 creates the screen display data for selecting modified package. More specifically, the package updating unit 336 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Further, the package updating unit 336 extracts the ID of the modified package that the identified user possesses. The package updating unit 336 refers to the modified package table stored in the server storage unit 32 by using the extracted modified package ID as the key, and extracts the name of the corresponding modified package, the type of operation to be applied to the existing package, and the ID of each included reward. Next, the package updating unit 336 refers to the reward table stored in the server storage unit 32 by using the ID of each identified reward as the key, and extracts the name of the corresponding reward and the filename of the associated image data. Then, the package updating unit 336 creates the screen display data for selecting modified package, including the extracted modified package ID and the received user ID, etc., for displaying the name of the modified package identified by the extracted ID, the type of operation, the name of each reward, the image designated by its filename, the numbers, the radio button for accepting the modified package selection instruction, the button for accepting the selected modified package application instruction, etc., in a prescribed layout.

On the other hand, if the type of instruction is not the “modified package selection”, that is, if it is the “modified package application”, the package updating unit 336 applies the selected modified package to the package. More specifically, the package updating unit 336 refers to the modified package table stored in the server storage unit 32 by using the received modified package ID as the key, and identifies the corresponding modified package. Further, the package updating unit 336 extracts the type of operation to be applied to the existing package by the identified modified package. If the type of operation thus extracted is the “addition”, the package updating unit 336 extracts the ID of each reward included in the identified modified package. Next, the package updating unit 336 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Then, the package updating unit 336 stores the extracted reward ID as the ID of the reward included in the identified user's package. The package updating unit 336 sets the corresponding giving status to “not-yet-given”.

On the other hand, if the type of operation is the “deletion”, the package updating unit 336 extracts the ID of each reward included in the identified modified package. Next, the package updating unit 336 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Further, the package updating unit 336 refers to the giving status of the rewards included in the identified user's package, and identifies “not-yet-given” rewards. Then, the package updating unit 336 matches the extracted reward ID against the IDs of the identified rewards, and changes the giving status of the first matching reward to “deleted”.

On the other hand, if the type of operation is neither of the above, that is, if it is the “replacement”, the package updating unit 336 extracts the ID of the reward to be replaced and the ID of the replaced reward included in the identified modified package. Next, the package updating unit 336 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Further, the package updating unit 336 refers to the giving status of the rewards included in the identified user's package, and identifies “not-yet-given” rewards. Then, the package updating unit 336 matches the extracted ID of the reward to be replaced against the IDs of the identified rewards, and replaces the first matching reward ID by the replaced reward ID. The package updating unit 336 does not change the corresponding giving status.

The package updating unit 336 deletes the received modified package ID from the list of the IDs of the modified packages that the identified user possesses.

The package updating unit 336 creates the screen display data for updating package. More specifically, the package updating unit 336 refers to the giving status of the rewards included in the identified user's package, and identifies “not-yet-given” and “given” rewards, respectively. Next, the package updating unit 336 refers to the reward table stored in the server storage unit 32 by using the ID of each identified reward as the key, and extracts the name of the corresponding reward and the filename of the associated image data. Then, the package updating unit 336 creates the screen display data for updating package, including the received user ID, etc., for displaying the name of each identified reward, the image designated by its filename, the numbers (the number of pieces not yet given versus the sum of the number of pieces so far given and the number of pieces not yet given), the text to the effect that the package has been updated, the button for accepting the “return to home screen” instruction, etc., in a prescribed layout.

The package updating unit 336 may create screen display data for updating package for displaying the reward winning status, not the reward remaining status. In this case, the package updating unit 336 creates screen display data for updating package for displaying the numbers of rewards (the number of pieces so far given versus the sum of the number of pieces so far given and the number of pieces not yet given).

The package updating unit 336 terminates the process after returning the created screen display data for selecting modified package, etc., to the game proceeding unit 333.

The process performed by the package resetting unit 337 will be described below. The package resetting unit 337 resets the package, tabulates the rewards included in the package, and creates display data for the package resetting screen that displays the results.

The package resetting unit 337 resets the package. More specifically, the package resetting unit 337 refers to the user table stored in the server storage unit 32 by using the received user ID as the key, and identifies the corresponding user. Next, the package resetting unit 337 refers to the giving status of the rewards included in the identified user's package, and identifies “given” or “deleted” rewards. Then, the package resetting unit 337 changes the giving status of each identified reward to “not-yet-given”.

The package resetting unit 337 creates the screen display data for resetting package. More specifically, the package resetting unit 337 identifies the rewards included in the identified user's package. Next, the package resetting unit 337 refers to the reward table stored in the server storage unit 32 by using the ID of each identified reward as the key, and extracts the name of the corresponding reward and the filename of the associated image data. Then, the package resetting unit 337 creates the screen display data for resetting package, including the received user ID, etc., for displaying the name of each identified reward, the image designated by its filename, the numbers (total number/total number), the text to the effect that the package has been reset, the button for accepting the “return to home screen” instruction, etc., in a prescribed layout.

The package resetting unit 337 may create screen display data for resetting package for displaying the reward winning status, not the reward remaining status. In this case, the package resetting unit 337 creates screen display data for resetting package for displaying the numbers of rewards (0 / total number).

The package resetting unit 337 terminates the process after returning the created screen display data for resetting package to the game proceeding unit 333.

As has been described above, by making it possible to apply various types of operation such as the addition of rewards to the existing package, the flexibility of the reward winning game can be enhanced, and this serves to maintain the user's interest in the game.

The present invention is not limited to the above specific embodiment. For example, in the above embodiment, it has been described that the modified package is obtained by playing a battle game, but the modified package may be obtained by other means. For example, it may be obtained by playing another reward winning game or clearing a mission (the so-called “quest”) requested by a character (the so-called NPC (Non-Player Character)) operated by a computer, or by participating in an event (for example, a RAID battle) by organizing a team with other users. Further, packages with different rarity levels may be obtained according to the degree of difficulty of the quest, event, etc. For example, a package with a higher rarity level may be obtained as the degree of difficulty of the quest, event, etc., increases. Further, packages with different rarity levels may be obtained according to the number of user logins, the number of executions of the reward winning game, etc. For example, a package with a higher rarity level may be obtained as the number of user logins, the number of executions of the reward winning game, or the like increases.

Further, in the above embodiment, it has been described that there are three types of modified package, i.e., the addition package, the deletion package, and the replacement package, but only one or two of them may be made available. Furthermore, these packages may be combined into one package so that the various types of operation can be applied by using the one package.

A computer program for causing a computer to execute the respective functions of the device processing unit 25 and the server processing unit 33 may be provided in a form recorded on a computer readable recording medium such as a magnetic recording medium or an optical recording medium.
